Appli cati onfiled J'nne3,1915. seriai vo. 31,861. p i I To all whom it may concern: I

Be it known that I, HARRY BENHAM, a citizen of the United States, residing at Chicago, in the county of Coolgstate of Illinois, have invented a new and useful Hernial Truss, of which thefollowing is a specification. q I

My invention consists of a hernial truss composed of a plurality of springs with which are connected respectively front and rear pads of the truss, an axial joint connecting said springs, a hip extension on the front-pad spring, and a connection for said extension with the rear of the truss, producing superior results in the adjustment, action and wear of the truss, thecontacting faces of the springs of the front and rear pads being provided with meansintegral with the same adapted to interlock at said-joint, whereby the springs at the latter are prevented from slipping or shifting, and so changing the adjustment, more particularly of the front pad.

The invention is satisfactorily illustrated in the accompanying drawing, but the'important instrumentalities thereof may be varied, as long as they are included 1n the of pro ect1ng teeth 10 on one spring, and

scope of the claims.

Figure 1 represents a perspective view 1 of a hernial truss embodying my 1nvention. Fig. 2 represents a section of a portion on line mm Fig. 1. Fig. 3 represents an elevation of the inner face of one of the springs of the truss. Fig. 4 represents an elevation of the inner face of the other spring of the truss. Fig. 5 represents a longitudinal section of a portion of what is shown in Fig. 3, on an enlarged scale.

Fig. 6 represents a longitudinal section'of a portion of what is shown in Fig. 4, on an enlarged scale.

Similar numerals of reference indicate corresponding parts in the figures. I Referring to the drawings. a spring or resilient piece to which is attached the frontpad 2, the latterbeing adapted to press the rupture ring.

3 designates an auxiliary 'sprlng or resilient piece to which is attached the back 'pad 4;. The springs 3 and 1 are connected at the side of the truss by the screw 5 which thus forms a pivotal connection and axis of said springs, permitting. the latter to be 1 designates {turned on each other and so be raised and lowered to adjust the pads in position.

The spring 1 is continued downwardly.

from the screw 5 by the piece 6 forming the hip extension of the truss with the lower portion of which said piece 6 is adjustably attachable as at 7,-the short elastic strap 8 which extends obliquely therefrom to the back pad at with which it is connectible as at 9, it being evident that by proper manipulation of the hip piece 6, the spring 1 particula'rlymay be turned on its axis, whereby the front pad 2 may be adjusted to the rupture ring so as to exert proper pressure thereon without severity, as a great portion 1 of usual pressure is avoided, while the truss may be worn with the greatest comfort. Then the strap 8 is fastened to the hip extension, and so under ordinary circumstances, the pad 2 retains its adjusted position but as the springs are liable to turn on each other at their axial connection 5 and so destroy the adjustment of the springs 1 and 3, I form interlocking means on the inner face of the spring 1 and the inner face of the spring 3 about the place of occupation of the, screw 5, said means consisting depressed serrations or teeth 11 on the other spring centered from the openings in the spring occupied by thescrew 5, the teeth 10 being adapted to enter the teeth 11, and so engage especially when the screw is tightened increasing the friction of the joint and so onespringwill not slip on the other, but when the screw is loosened the springs sep arate and the teeth disengage, when the springsmay be moved on each other for purposes requiring the same, without inter- 'ference of the teeth. Attention is also di rected to the fact that as the teeth 10 and 11 are on the opposite inner faces of the springs they are covered and concealed and do not present themselves for contact of the hands or garments of the wearer.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is

1. In a truss, a plurality of springs, front and rear pads respectively on said springs, a device adapted to'connect said springs and form a pivotal joint therefor, a hip extension of the front spring, a connection for j!s ecifi ii t m. Paramecium.16,1915. I

spectively front and rear pads on said sprlngs, a screw connectlng sa d sprlngs forming an axial joint therefor, a hip eX- 1 tension of the front'spring, a connection for Copies of this patent may be obtained for five cen said extension with the rear of the truss, the opposite inner faces of said springs about said'oonnecting screw having thereon teeth integral With the respective springs adapted "to interlock controlled by said 15 screw;
